The sheriff's office received an emergency call from a home on North 10th St. in Alton about 11 p.m. on Tuesday. The caller told deputies her family had locked themselves in the home to avoid her son-in-law, who was armed with a handgun.

She said the man was behaving in a threatening manner and was trying to break into the home.

Sheriff’s officials have identified the suspect as 40-year-old Antoine Tobias.

By the time deputies arrived, they said Tobias had forced his way inside the residence, where his wife, two children, mother-in-law and step father-in-law were. The officers surrounded the home in an effort to determine exactly where Tobias was located.

With the residence surrounded, a deputy near a bathroom window made contact with the family and helped those individuals get to safety.

A short time later, officials said, Tobias exited the house through the same window. Investigators said he was armed with a handgun and fired several rounds at deputies, who fired back.

Tobias was struck multiple times and was also bitten by a K-9 dog during the incident.

He was taken by ambulance to University Hospital in New Orleans, where his condition was not known. Officials said his injuries are not thought to be life threatening.

Upon his release from the hospital, Tobias will be booked into the St. Tammany Parish Jail on one count of aggravated burglary and two counts of attempted murder of a police officer.
